-Google C++ Testing Framework
-============================
-
-http://code.google.com/p/googletest/
-
-Overview
---------
-
-Google's framework for writing C++ tests on a variety of platforms
-(Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
-xUnit architecture.  Supports automatic test discovery, a rich set of
-assertions, user-defined assertions, death tests, fatal and non-fatal
-failures, various options for running the tests, and XML test report
-generation.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
-join us!
-
-Requirements for End Users
---------------------------
-
-Google Test is designed to have fairly minimal requirements to build
-and use with your projects, but there are some.  Currently, we support
-Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
-effort to support other platforms (e.g. Solaris, AIX, and z/OS).
-However, since core members of the Google Test project have no access
-to these platforms, Google Test may have outstanding issues there.  If
-you notice any problems on your platform, please notify
-googletestframework@googlegroups.com.  Patches for fixing them are
-even more welcome!
-
-### Linux Requirements ###
-
-These are the base requirements to build and use Google Test from a source
-package (as described below):
-  * GNU-compatible Make or gmake
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * A C++98-standard-compliant compiler
-
-### Windows Requirements ###
-
-  * Microsoft Visual C++ 7.1 or newer
-
-### Cygwin Requirements ###
-
-  * Cygwin 1.5.25-14 or newer
-
-### Mac OS X Requirements ###
-
-  * Mac OS X 10.4 Tiger or newer
-  * Developer Tools Installed
-
-Also, you'll need CMake 2.6.4 or higher if you want to build the
-samples using the provided CMake script, regardless of the platform.
-
-Requirements for Contributors
------------------------------
-
-We welcome patches.  If you plan to contribute a patch, you need to
-build Google Test and its own tests from an SVN checkout (described
-below), which has further requirements:
-
-  * Python version 2.3 or newer (for running some of the tests and
-    re-generating certain source files from templates)
-  * CMake 2.6.4 or newer
-
-Getting the Source
-------------------
-
-There are two primary ways of getting Google Test's source code: you
-can download a stable source release in your preferred archive format,
-or directly check out the source from our Subversion (SVN) repositary.
-The SVN checkout requires a few extra steps and some extra software
-packages on your system, but lets you track the latest development and
-make patches much more easily, so we highly encourage it.
-
-### Source Package ###
-
-Google Test is released in versioned source packages which can be
-downloaded from the download page [1].  Several different archive
-formats are provided, but the only difference is the tools used to
-manipulate them, and the size of the resulting file.  Download
-whichever you are most comfortable with.
-
-  [1] http://code.google.com/p/googletest/downloads/list
-
-Once the package is downloaded, expand it using whichever tools you
-prefer for that type.  This will result in a new directory with the
-name "gtest-X.Y.Z" which contains all of the source code.  Here are
-some examples on Linux:
-
-  tar -xvzf gtest-X.Y.Z.tar.gz
-  tar -xvjf gtest-X.Y.Z.tar.bz2
-  unzip gtest-X.Y.Z.zip
-
-### SVN Checkout ###
-
-To check out the main branch (also known as the "trunk") of Google
-Test, run the following Subversion command:
-
-  svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
-
-Setting up the Build
---------------------
-
-To build Google Test and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-### Generic Build Instructions ###
-
-Suppose you put Google Test in directory ${GTEST_DIR}.  To build it,
-create a library build target (or a project as called by Visual Studio
-and Xcode) to compile
-
-  ${GTEST_DIR}/src/gtest-all.cc
-
-with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR}
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-      -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-  ar -rv libgtest.a gtest-all.o
-
-(We need -pthread as Google Test uses threads.)
-
-Next, you should compile your test source file with
-${GTEST_DIR}/include in the system header search path, and link it
-with gtest and any other necessary libraries:
-
-  g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
-      -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Test on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Test's own tests.  Instead, it just builds the Google Test library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-  cd ${GTEST_DIR}/make
-  make
-  ./sample1_unittest
-
-If you see errors, try to tweak the contents of make/Makefile to make
-them go away.  There are instructions in make/Makefile on how to do
-it.
-
-### Using CMake ###
-
-Google Test comes with a CMake build script (CMakeLists.txt) that can
-be used on a wide range of platforms ("C" stands for cross-platofrm.).
-If you don't have CMake installed already, you can download it for
-free from http://www.cmake.org/.
-
-CMake works by generating native makefiles or build projects that can
-be used in the compiler environment of your choice.  The typical
-workflow starts with:
-
-  mkdir mybuild       # Create a directory to hold the build output.
-  cd mybuild
-  cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the
-last command with
-
-  cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a *nix system, you should now see a Makefile in the
-current directory.  Just type 'make' to build gtest.
-
-If you use Windows and have Vistual Studio installed, a gtest.sln file
-and several .vcproj files will be created.  You can then build them
-using Visual Studio.
-
-On Mac OS X with Xcode installed, a .xcodeproj file will be generated.
-
-### Legacy Build Scripts ###
-
-Before settling on CMake, we have been providing hand-maintained build
-projects/scripts for Visual Studio, Xcode, and Autotools.  While we
-continue to provide them for convenience, they are not actively
-maintained any more.  We highly recommend that you follow the
-instructions in the previous two sections to integrate Google Test
-with your existing build system.
-
-If you still need to use the legacy build scripts, here's how:
-
-The msvc\ folder contains two solutions with Visual C++ projects.
-Open the gtest.sln or gtest-md.sln file using Visual Studio, and you
-are ready to build Google Test the same way you build any Visual
-Studio project.  Files that have names ending with -md use DLL
-versions of Microsoft runtime libraries (the /MD or the /MDd compiler
-option).  Files without that suffix use static versions of the runtime
-libraries (the /MT or the /MTd option).  Please note that one must use
-the same option to compile both gtest and the test code.  If you use
-Visual Studio 2005 or above, we recommend the -md version as /MD is
-the default for new projects in these versions of Visual Studio.
-
-On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using
-Xcode.  Build the "gtest" target.  The universal binary framework will
-end up in your selected build directory (selected in the Xcode
-"Preferences..." -> "Building" pane and defaults to xcode/build).
-Alternatively, at the command line, enter:
-
-  xcodebuild
-
-This will build the "Release" configuration of gtest.framework in your
-default build location.  See the "xcodebuild" man page for more
-information about building different configurations and building in
-different locations.
-
-If you wish to use the Google Test Xcode project with Xcode 4.x and
-above, you need to either:
- * update the SDK configuration options in xcode/Config/General.xconfig.
-   Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If
-   you choose this route you lose the ability to target earlier versions
-   of MacOS X.
- * Install an SDK for an earlier version. This doesn't appear to be
-   supported by Apple, but has been reported to work
-   (http://stackoverflow.com/questions/5378518).
-
-Tweaking Google Test
---------------------
-
-Google Test can be used in diverse environments.  The default
-configuration may not work (or may not work well) out of the box in
-some environments.  However, you can easily tweak Google Test by
-defining control macros on the compiler command line.  Generally,
-these macros are named like GTEST_XYZ and you define them to either 1
-or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below.  For a complete list,
-see file include/gtest/internal/gtest-port.h.
-
-### Choosing a TR1 Tuple Library ###
-
-Some Google Test features require the C++ Technical Report 1 (TR1)
-tuple library, which is not yet available with all compilers.  The
-good news is that Google Test implements a subset of TR1 tuple that's
-enough for its own need, and will automatically use this when the
-compiler doesn't provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test
-uses.  However, if your project already uses TR1 tuple, you need to
-tell Google Test to use the same TR1 tuple library the rest of your
-project uses, or the two tuple implementations will clash.  To do
-that, add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test and your tests.  If
-you want to force Google Test to use its own tuple library, just add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you don't want Google Test to use tuple at all, add
-
-  -DGTEST_HAS_TR1_TUPLE=0
-
-and all features using tuple will be disabled.
-
-### Multi-threaded Tests ###
-
-Google Test is thread-safe where the pthread library is available.
-After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE
-macro to see whether this is the case (yes if the macro is #defined to
-1, no if it's undefined.).
-
-If Google Test doesn't correctly detect whether pthread is available
-in your environment, you can force it with
-
-  -DGTEST_HAS_PTHREAD=1
-
-or
-
-  -DGTEST_HAS_PTHREAD=0
-
-When Google Test uses pthread, you may need to add flags to your
-compiler and/or linker to select the pthread library, or you'll get
-link errors.  If you use the CMake script or the deprecated Autotools
-script, this is taken care of for you.  If you use your own build
-script, you'll need to read your compiler and linker's manual to
-figure out what flags to add.
-
-### As a Shared Library (DLL) ###
-
-Google Test is compact, so most users can build and link it as a
-static library for the simplicity.  You can choose to use Google Test
-as a shared library (known as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-  -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags.  You'll also need to tell the linker to produce
-a shared library instead - consult your linker's manual for how to do
-it.
-
-To compile your *tests* that use the gtest shared library, add
-
-  -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when
-using some compilers (e.g. GCC), they may become necessary in the
-future, if we decide to improve the speed of loading the library (see
-http://gcc.gnu.org/wiki/Visibility for details).  Therefore you are
-recommended to always add the above flags when using Google Test as a
-shared library.  Otherwise a future release of Google Test may break
-your build script.
-
-### Avoiding Macro Name Clashes ###
-
-In C++, macros don't obey namespaces.  Therefore two libraries that
-both define a macro of the same name will clash if you #include both
-definitions.  In case a Google Test macro clashes with another
-library, you can force Google Test to rename its macro to avoid the
-conflict.
-
-Specifically, if both Google Test and some other code define macro
-FOO, you can add
-
-  -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell Google Test to change the macro's name
-from FOO to GTEST_FOO.  Currently FOO can be FAIL, SUCCEED, or TEST.
-For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write
-
-  GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-  TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.
-
-Upgrating from an Earlier Version
----------------------------------
-
-We strive to keep Google Test releases backward compatible.
-Sometimes, though, we have to make some breaking changes for the
-users' long-term benefits.  This section describes what you'll need to
-do if you are upgrading from an earlier version of Google Test.
-
-### Upgrading from 1.3.0 or Earlier ###
-
-You may need to explicitly enable or disable Google Test's own TR1
-tuple library.  See the instructions in section "Choosing a TR1 Tuple
-Library".
-
-### Upgrading from 1.4.0 or Earlier ###
-
-The Autotools build script (configure + make) is no longer officially
-supportted.  You are encouraged to migrate to your own build system or
-use CMake.  If you still need to use Autotools, you can find
-instructions in the README file from Google Test 1.4.0.
-
-On platforms where the pthread library is available, Google Test uses
-it in order to be thread-safe.  See the "Multi-threaded Tests" section
-for what this means to your build script.
-
-If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google
-Test will no longer compile.  This should affect very few people, as a
-large portion of STL (including <string>) doesn't compile in this mode
-anyway.  We decided to stop supporting it in order to greatly simplify
-Google Test's implementation.
-
-Developing Google Test
-----------------------
-
-This section discusses how to make your own changes to Google Test.
-
-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-  mkdir mybuild
-  cd mybuild
-  cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python ("Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)"), try telling it explicitly where your Python
-executable can be found:
-
-  cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On *nix,
-this is usually done by 'make'.  To run the tests, do
-
-  make test
-
-All tests should pass.
-
-### Regenerating Source Files ###
-
-Some of Google Test's source files are generated from templates (not
-in the C++ sense) using a script.  A template file is named FOO.pump,
-where FOO is the name of the file it will generate.  For example, the
-file include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-Normally you don't need to worry about regenerating the source files,
-unless you need to modify them.  In that case, you should modify the
-corresponding .pump files instead and run the pump.py Python script to
-regenerate them.  You can find pump.py in the scripts/ directory.
-Read the Pump manual [2] for how to use it.
-
-  [2] http://code.google.com/p/googletest/wiki/PumpManual
-
-### Contributing a Patch ###
-
-We welcome patches.  Please read the Google Test developer's guide [3]
-for how you can contribute.  In particular, make sure you have signed
-the Contributor License Agreement, or we won't be able to accept the
-patch.
-

+these macros are named like `GTEST_XYZ` and you define them to either 1
+or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below.  For a complete list,
+see file [include/gtest/internal/gtest-port.h](include/gtest/internal/gtest-port.h).
+
+### Choosing a TR1 Tuple Library ###
+
+Some Google Test features require the C++ Technical Report 1 (TR1)
+tuple library, which is not yet available with all compilers.  The
+good news is that Google Test implements a subset of TR1 tuple that's
+enough for its own need, and will automatically use this when the
+compiler doesn't provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+uses.  However, if your project already uses TR1 tuple, you need to
+tell Google Test to use the same TR1 tuple library the rest of your
+project uses, or the two tuple implementations will clash.  To do
+that, add
+
+    -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test and your tests.  If
+you want to force Google Test to use its own tuple library, just add
+
+    -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you don't want Google Test to use tuple at all, add
+
+    -DGTEST_HAS_TR1_TUPLE=0
+
+and all features using tuple will be disabled.
+
+### Multi-threaded Tests ###
+
+Google Test is thread-safe where the pthread library is available.
+After `#include "gtest/gtest.h"`, you can check the `GTEST_IS_THREADSAFE`
+macro to see whether this is the case (yes if the macro is `#defined` to
+1, no if it's undefined.).
+
+If Google Test doesn't correctly detect whether pthread is available
+in your environment, you can force it with
+
+    -DGTEST_HAS_PTHREAD=1
+
+or
+
+    -DGTEST_HAS_PTHREAD=0
+
+When Google Test uses pthread, you may need to add flags to your
+compiler and/or linker to select the pthread library, or you'll get
+link errors.  If you use the CMake script or the deprecated Autotools
+script, this is taken care of for you.  If you use your own build
+script, you'll need to read your compiler and linker's manual to
+figure out what flags to add.
+
+### As a Shared Library (DLL) ###
+
+Google Test is compact, so most users can build and link it as a
+static library for the simplicity.  You can choose to use Google Test
+as a shared library (known as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+    -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags.  You'll also need to tell the linker to produce
+a shared library instead - consult your linker's manual for how to do
+it.
+
+To compile your *tests* that use the gtest shared library, add
+
+    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when
+using some compilers (e.g. GCC), they may become necessary in the
+future, if we decide to improve the speed of loading the library (see
+<http://gcc.gnu.org/wiki/Visibility> for details).  Therefore you are
+recommended to always add the above flags when using Google Test as a
+shared library.  Otherwise a future release of Google Test may break
+your build script.
+
+### Avoiding Macro Name Clashes ###
+
+In C++, macros don't obey namespaces.  Therefore two libraries that
+both define a macro of the same name will clash if you `#include` both
+definitions.  In case a Google Test macro clashes with another
+library, you can force Google Test to rename its macro to avoid the
+conflict.
+
+Specifically, if both Google Test and some other code define macro
+FOO, you can add
+
+    -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell Google Test to change the macro's name
+from `FOO` to `GTEST_FOO`.  Currently `FOO` can be `FAIL`, `SUCCEED`,
+or `TEST`.  For example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll
+need to write
+
+    GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+    TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.
+
+## Developing Google Test ##
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+    mkdir mybuild
+    cd mybuild
+    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python.  If the cmake command complains about not being
+able to find Python (`Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
+executable can be found:
+
+    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests.  On \*nix,
+this is usually done by 'make'.  To run the tests, do
+
+    make test
+
+All tests should pass.
+
+Normally you don't need to worry about regenerating the source files,
+unless you need to modify them.  In that case, you should modify the
+corresponding .pump files instead and run the pump.py Python script to
+regenerate them.  You can find pump.py in the [scripts/](scripts/) directory.
+Read the [Pump manual](docs/PumpManual.md) for how to use it.

+// The following macros are useful for writing death tests.
+
+// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
+// executed:
+//
+//   1. It generates a warning if there is more than one active
+//   thread.  This is because it's safe to fork() or clone() only
+//   when there is a single thread.
+//
+//   2. The parent process clone()s a sub-process and runs the death
+//   test in it; the sub-process exits with code 0 at the end of the
+//   death test, if it hasn't exited already.
+//
+//   3. The parent process waits for the sub-process to terminate.
+//
+//   4. The parent process checks the exit code and error message of
+//   the sub-process.
+//
+// Examples:
+//
+//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+//   for (int i = 0; i < 5; i++) {
+//     EXPECT_DEATH(server.ProcessRequest(i),
+//                  "Invalid request .* in ProcessRequest()")
+//                  << "Failed to die on request " << i;
+//   }
+//
+//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+//   bool KilledBySIGHUP(int exit_code) {
+//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+//   }
+//
+//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
+//   which uses the POSIX extended regex syntax.
+//
+//   On other platforms (e.g. Windows), we only support a simple regex
+//   syntax implemented as part of Google Test.  This limited
+//   implementation should be enough most of the time when writing
+//   death tests; though it lacks many features you can find in PCRE
+//   or POSIX extended regex syntax.  For example, we don't support
+//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+//   repetition count ("x{5,7}"), among others.
+//
+//   Below is the syntax that we do support.  We chose it to be a
+//   subset of both PCRE and POSIX extended regex, so it's easy to
+//   learn wherever you come from.  In the following: 'A' denotes a
+//   literal character, period (.), or a single \\ escape sequence;
+//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
+//   natural numbers.
+//
+//     c     matches any literal character c
+//     \\d   matches any decimal digit
+//     \\D   matches any character that's not a decimal digit
+//     \\f   matches \f
+//     \\n   matches \n
+//     \\r   matches \r
+//     \\s   matches any ASCII whitespace, including \n
+//     \\S   matches any character that's not a whitespace
+//     \\t   matches \t
+//     \\v   matches \v
+//     \\w   matches any letter, _, or decimal digit
+//     \\W   matches any character that \\w doesn't match
+//     \\c   matches any literal character c, which must be a punctuation
+//     .     matches any single character except \n
+//     A?    matches 0 or 1 occurrences of A
+//     A*    matches 0 or many occurrences of A
+//     A+    matches 1 or many occurrences of A
+//     ^     matches the beginning of a string (not that of each line)
+//     $     matches the end of a string (not that of each line)
+//     xy    matches x followed by y
+//
+//   If you accidentally use PCRE or POSIX extended regex features
+//   not implemented by us, you will get a run-time failure.  In that
+//   case, please try to rewrite your regular expression within the
+//   above syntax.
+//
+//   This implementation is *not* meant to be as highly tuned or robust
+//   as a compiled regex library, but should perform well enough for a
+//   death test, which already incurs significant overhead by launching
+//   a child process.
+//
+// Known caveats:
+//
+//   A "threadsafe" style death test obtains the path to the test
+//   program from argv[0] and re-executes it in the sub-process.  For
+//   simplicity, the current implementation doesn't search the PATH
+//   when launching the sub-process.  This means that the user must
+//   invoke the test program via a path that contains at least one
+//   path separator (e.g. path/to/foo_test and
+//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
+//   is rarely a problem as people usually don't put the test binary
+//   directory in PATH.
+//

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+  // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+  // Inside a test, access the test parameter with the GetParam() method
+  // of the TestWithParam<T> class:
+  EXPECT_TRUE(foo.Blah(GetParam()));
+  ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+  ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a  summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".
+

+                        FooTest,

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//

+//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//

+// with parameter values "cat" and "dog":

+//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+  // You can inherit all the usual members for a non-parameterized test
+  // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
+  // The usual test fixture members go here too.
+};
+
+TEST_F(BaseTest, HasFoo) {
+  // This is an ordinary non-parameterized test.
+}

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+  // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+  // Inside a test, access the test parameter with the GetParam() method
+  // of the TestWithParam<T> class:
+  EXPECT_TRUE(foo.Blah(GetParam()));
+  ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+  ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a  summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".

+                        FooTest,

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:

+//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//

+// with parameter values "cat" and "dog":

+//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+  // You can inherit all the usual members for a non-parameterized test
+  // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T.  More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+//   1. foo::PrintTo(const T&, ostream*)
+//   2. operator<<(ostream&, const T&) defined in either foo or the
+//      global namespace.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+//   // Prints a value to a string.  For a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   std::string ::testing::PrintToString(const T& value);
+//
+//   // Prints a value tersely: for a reference type, the referenced
+//   // value (but not the address) is printed; for a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+//   // Prints value using the type inferred by the compiler.  The difference
+//   // from UniversalTersePrint() is that this function prints both the
+//   // pointer and the NUL-terminated string for a (const or not) char pointer.
+//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+//   // Prints the fields of a tuple tersely to a string vector, one
+//   // element for each field. Tuple support must be enabled in
+//   // gtest-port.h.
+//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+//       const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container.  When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect.  In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator.  We'll fix this if there's an
+// actual need for it.  Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// the macro to parse correctly.
+typedef testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_CASE(FooTest, MyTypes);
+
+// If the type list contains only one type, you can write that type
+// directly without Types<...>:
+//   TYPED_TEST_CASE(FooTest, int);
+
+// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
+// tests for this test case as you want.
+TYPED_TEST(FooTest, DoesBlah) {
+  // Inside a test, refer to TypeParam to get the type parameter.
+  // Since we are inside a derived class template, C++ requires use to
+  // visit the members of FooTest via 'this'.

+  // To visit static members of the fixture, add the TestFixture::
+  // prefix.
+  n += TestFixture::shared_;
+
+  // To refer to typedefs in the fixture, add the "typename
+  // TestFixture::" prefix.
+  typename TestFixture::List values;

+}
+
+TYPED_TEST(FooTest, HasPropertyA) { ... }
+
+#endif  // 0
+
+// Type-parameterized tests are abstract test patterns parameterized
+// by a type.  Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are.  The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have.  Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly.  Here's an example:
+
+#if 0
+
+// First, define a fixture class template.  It should be parameterized
+// by a type.  Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+  ...
+};
+
+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_CASE_P(FooTest);
+
+// Then, use TYPED_TEST_P() to define as many type-parameterized tests
+// for this type-parameterized test case as you want.
+TYPED_TEST_P(FooTest, DoesBlah) {
+  // Inside a test, refer to TypeParam to get the type parameter.
+  TypeParam n = 0;

-// even more welcome!).
-//
-// Note that it is possible that none of the GTEST_OS_* macros are defined.
-//
-// Macros indicating available Google Test features (defined to 1 if
-// the corresponding feature is supported; otherwise undefined):

-//                            define themselves.
-//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
-//                            the above two are mutually exclusive.
-//   GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
-//
-// Macros for basic C++ coding:
-//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
-//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
-//                              variable don't have to be used.

-//                         synchronization primitives have real implementations
-//                         and Google Test is thread-safe; or 0 otherwise.
-//
-// Template meta programming:
-//   is_pointer     - as in TR1; needed on Symbian and IBM XL C/C++ only.
-//   IteratorTraits - partial implementation of std::iterator_traits, which
-//                    is not available in libCstd when compiled with Sun C++.
-//
-// Smart pointers:
-//   scoped_ptr     - as in TR2.
-//
-// Regular expressions:
-//   RE             - a simple regular expression class using the POSIX
-//                    Extended Regular Expression syntax on UNIX-like
-//                    platforms, or a reduced regular exception syntax on
-//                    other platforms, including Windows.
-//
-// Logging:
-//   GTEST_LOG_()   - logs messages at the specified severity level.

-//   CaptureStderr()     - starts capturing stderr.
-//   GetCapturedStderr() - stops capturing stderr and returns the captured
-//                         string.
-//
-// Integer types:
-//   TypeWithSize   - maps an integer to a int type.
-//   Int32, UInt32, Int64, UInt64, TimeInMillis
-//                  - integers of known sizes.
-//   BiggestInt     - the biggest signed integer type.
-//
-// Command-line utilities:
-//   GTEST_FLAG()       - references a flag.
-//   GTEST_DECLARE_*()  - declares a flag.
-//   GTEST_DEFINE_*()   - defines a flag.
-//   GetInjectableArgvs() - returns the command line as a vector of strings.

-//   expr is a compile-time constant.  (Template arguments must be
-//   determined at compile-time.)
-//
-// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
-//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written

-//     CompileAssert<bool(expr)>

-// Use ImplicitCast_ as a safe version of static_cast for upcasting in
-// the type hierarchy (e.g. casting a Foo* to a SuperclassOfFoo* or a
-// const Foo*).  When you use ImplicitCast_, the compiler checks that
-// the cast is safe.  Such explicit ImplicitCast_s are necessary in
-// surprisingly many situations where C++ demands an exact type match
-// instead of an argument type convertable to a target type.
-//
-// The syntax for using ImplicitCast_ is the same as for static_cast:
-//
-//   ImplicitCast_<ToType>(expr)
-//
-// ImplicitCast_ would have been part of the C++ standard library,
-// but the proposal was submitted too late.  It will probably make
-// its way into the language in the future.
-//
-// This relatively ugly name is intentional. It prevents clashes with
-// similar functions users may have (e.g., implicit_cast). The internal
-// namespace alone is not enough because the function can be found by ADL.

-// When you upcast (that is, cast a pointer from type Foo to type
-// SuperclassOfFoo), it's fine to use ImplicitCast_<>, since upcasts
-// always succeed.  When you downcast (that is, cast a pointer from
-// type Foo to type SubclassOfFoo), static_cast<> isn't safe, because
-// how do you know the pointer is really of type SubclassOfFoo?  It
-// could be a bare Foo, or of type DifferentSubclassOfFoo.  Thus,
-// when you downcast, you should use this macro.  In debug mode, we
-// use dynamic_cast<> to double-check the downcast is legal (we die
-// if it's not).  In normal mode, we do the efficient static_cast<>
-// instead.  Thus, it's important to test in debug mode to make sure
-// the cast is legal!
-//    This is the only place in the code we should use dynamic_cast<>.
-// In particular, you SHOULDN'T be using dynamic_cast<> in order to
-// do RTTI (eg code like this:
-//    if (dynamic_cast<Subclass1>(foo)) HandleASubclass1Object(foo);

-// We don't want to require the users to write TemplatesN<...> directly,
-// as that would require them to count the length.  Templates<...> is much
-// easier to write, but generates horrible messages when there is a
-// compiler error, as gcc insists on printing out each template
-// argument, even if it has the default value (this means Templates<list>
-// will appear as Templates<list, NoneT, NoneT, ..., NoneT> in the compiler
-// errors).
-//
-// Our solution is to combine the best part of the two approaches: a
-// user would write Templates<T1, ..., TN>, and Google Test will translate
-// that to TemplatesN<T1, ..., TN> internally to make error messages
-// readable.  The translation is done by the 'type' member of the
-// Templates template.
